MORSE CODE (CW)

INFORMATION:

Morse Code is a system of communication developed by Samuel F.B. Morse that uses a series of dots and dashes to relay coded messages. Having been used for over 160 years, it is older than any other electrical coded system. Morse Code is used in amateur radio in the form referred to as CW (continuous wave) in which the dots and dashes, or dits and dahs, are transmitted electronically as on and off tones in varying durations. Dit (dot) tones are on for the shortest duration. Dah (dash) tones are on for three times as long as dits (dots). CW is the original digital mode of communication as well as the most reliable method of transmitting weak signals during poor band conditions.

Each letter, number and punctuation mark is represented by a unique series of dits (dots) and/or dahs (dashes) as shown below:
